Which issue or RFC does this PR close?

Closes #2463

Rationale for this change

The G4-B evidence implementation was merged in #2506. Its remaining lifecycle dependency was completed by #2538, which closed #2462 and connected confirmed deadline, cancellation, disconnect, and shutdown stops to execution evidence. The validation record still described #2462 as open.

What changes are included in this PR?

• Update the bilingual Gateway evidence validation record to reflect the feat(gateway): enforce request deadlines, cancellation, and bounded shutdown #2538 lifecycle integration.
• Record that stopped calls preserve their confirmed stop reason and send state; interrupted handed-off attempts remain possibly_sent with unknown usage.
• Document the current validation results and distinguish local Gateway coverage from real-Core, hosted-provider, third-party-host, and external telemetry-backend checks.

No runtime code, HTTP contract, or generated files changed.

Are there any user-facing changes?

No runtime behavior changes.

How was this change tested?

• mise exec rust@1.95.0 -- cargo test --locked --workspace -- --skip real_core_capture_commit_loss_recovers_same_record_and_prepare_is_not_replayed — 247 passed; the real-Core test was skipped because PC_TEST_PYTHON and a running Python Core were unavailable.
• git diff --check — passed.
• The Python lifecycle E2E could not start in this checkout because the available Python environment imported a different workspace package. The feat(gateway): enforce request deadlines, cancellation, and bounded shutdown #2538 PR reports its lifecycle E2E results separately.
